It should be very difficult, never heard of that one before - was it a cheapo?

The axle is the heaviest part of the BB and is usually over built from steel for strength.

How heavy are you.....?

Serious thread

HI threaded,

I am an avid cyclist myself and the same thing has happened to me. Basically I think that any sort of corrosion caused mainly by rain snow etc weakens the metal and then it will bend and then break. You can feel when its going to happen because the peddling gets dodgy about 10 km beforehand

You can change the part but I found that I couldnt get the remaining bit of the axlwe out of the frame. I went to Halfords and asked them to try and they couldnt do it either, but Halfords are cr@p. I eventually threw away the frame, becuase it was a cr@p bike anyway.

Best of luck and hope you are back on your bicycle soon

It was a slight incline and I was going for a "power up", so missed the goolies but the right buttock is quite bruised.

Never had the axle break like that, but I've had pedal cranks snap without warning, chain links break, and heard tell of someone whose handlebars came off in their hands as they were riding along. Ow. Don't know the age/providence of your bike, but could always be worth checking with the supplier, mentioning your popular website which illustrates the incident and names the manufacturer and supplier.

Are you sure you're not thinking of the opening credits of the Pink Panther Show?

A question for Shimano, and anyone else who knows about bikes: Just how hard is it to break the axle bar going through the bottom bracket and joins the two crank arms together?

'Cause I've broken it on one of my bikes, and now my knees really hurt, and I had to walk for fscking miles to get back home.

I've broken just about every breakable bit there is on a bike at some point, but never the crank shaft. Never seen or heard of it happening before, I'm impressed!

I'm guessing Zetghost is right and it's a stress fracture possibly due to a minor fault in the part. If it's a relatively new bike you might have some joy with the manufacturer, especially if you play up the injuries caused by the failure.
